Chinese system integrators have cemented their dominance of the global battery energy storage system (BESS) market, capturing 76% of global market share in 2025.

The state-owned Saudi Power Procurement Company (SPPC) has revealed the qualified bidders for its second build own operate (BOO) BESS tender, totalling 3GW/12GWh of capacity across six projects.

State of charge (SOC) is on the face of it a straightforward measurement for batteries and BESS. But in reality, it’s highly complex and under- or over-reporting still happens in the industry, leading to under-performance and losses in revenue.

In 2025, BESS installations surpassed 320GWh, a y-o-y increase of over 50%. While this tells one-side of the story, the growth in cell and system shipments tells an even more significant one, writes Benchmark’s Iola Hughes.

Envision has signed a 660MWh BESS supply agreement with SOLA Group and construction company WBHO in South Africa’s Free State.

‘Enhancing System Stability through Grid-Forming Energy Storage Technologies,’ has been launched by Energy-Storage.news, sponsor Kehua Digital Energy and TÜV Rheinland.

Around 4.9GW/14.6GWh of large-scale BESS came online in May, with a much more balanced regional breakdown than usual.

To avoid pitfalls that harm BESS investments, developers must sign well-structured contracts, writes Intertek CEA’s Yilin Huang.
